6 core challenges that researchers must consider as the race to create models that are ever closer to real human embryos heats up.

Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

Advances in organoids and embryonic models of human development have the potential to prompt social and existential questions—e.g., what defines human individuality? However, bioethicist Insoo Hyun of ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

Scientists have grown a human embryo-like structure in a lab which replicates very early human development - including the production of blood stem cells. The lab-grown embryo model could help ...

Under his microscope, Jun Wu could see several tiny spheres, each less than 1 millimetre wide. They looked just like human embryos: a dark cluster of cells surrounded by a cavity, and then another ...

IIIF provides researchers rich metadata and media viewing options for comparison of works across cultural heritage collections. Visit the IIIF page to learn more. This papier mache model of a human ...
